I totally forgot about the dual core vs the dual cpu. Still I think there is some kind of hardware acceleration for video.
Found it.

Toshiba to Launch World's Highest Performance 3D Graphics LSI for Mobile Phones
TOKYO--Toshiba Corporation today announced a dedicated 3D graphics LSI that will add previously unseen levels of realism and excitement to games played on mobile phones. The new LSI, "TC35711XBG", can render 100 mega-polygons*1 a second, a performance that far surpasses that of current handheld game consoles. Samples of the new graphics LSI will be available from October.
Toshiba's new chip integrates a new developed 3D graphics processor that achieves 38 times*2 the performance of existing products. Its extremely advanced capabilities open the way to further development of software applications of mobile phones. The new chip is also compatible with programmable shader*3, and its advanced rendering capabilities will bring realistic shading and reflectivity to mobile phones for the first time.
Alongside the new 3D graphics processor, the new LSI also integrates Toshiba's "Media Embedded Processor" (MeP) to handle sound, a host processor, a WVGA LCD controller for wide-screen displays, and brings all the essential components of a game console onto a single chip dedicated to enhancing mobile phone game performance.
With the launch of the high performance TC35711XBG, Toshiba will contribute to further development in games for mobile phones, while reinforcing its position as a technology and market leader in advanced LSI.
